CHURN.

SPECIFICATION forming part Of Letters Patent No. 443,410, dated December23, 1890.

Application filed March 281 1890. Serial No. 345,736i (Model.)

T0 all whom/'it iii/ty concern:

A Beit knownthat I, ISAAC HENRY' SHALL IBAUGH, a citizen ofthe UnitedStates, residing at Avilla, in the county of Noble and State ofIndiana,have invented certain new and useful Improvements in Churns; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart toiwhich it appertains to make and use the same.

This invention. relates to that class of churns in which the churn bodyand the dasher revolve in opposite directions.

The purpose of the invention is to provide mechanism which will beinterchangeable in Vits parts to vary the relative speed of the dasherand the churn-body.

The improvement consists of the novel features which will be hereinaftermore fully described and claimed, and which'are shown in the annexeddrawings, in which- Figure lis a perspective 4view of a churn embodyingmy invention. Fig. 2 is a vertical central section. Fig. is a detailView showing the churn differently speeded from Figs. l and 2.

The frame may be of anysuitable construction, and, as shown, comprisestwo standards A, having feet a and a cross-piece C, which connects andbraces the said standards. The churnbody,which maybe of any desiredshape, is preferably formed like a barrel, and is journaled at its sidesbetween the upper ends of the standards A. The journal D is tubular, andis secured to the churn-body, and on the outer end thereof is keyed orotherwise fastened the gear-wheelE. The journal F passes loosely throughthe side of the churn -body and is recessed at its inner end to receivethe projecting end of the spring-pressed pin G in the opposing end ofthe dasher-shaft. This pin is inserted in an opening or recess II in thedasher-shaft I, and has a collar g between its ends which engages withplate c', applied to the end of the dashenshaf tand through which thesaid pin projects. The outer end of recess H is sufficiently large toreceive the spring J, which is mounted on the inner end of pin G, andpermits a free movement of said spring and pin G. The spring J bearsagainst collar g and the inner end of the enlarged recess. Thedasher-shaft is provided at. the end opposite that which receivesjournal F, with journal I, which extends through the tubular journal D,and the masterwheel K is secured on the outer end of the said journal I.The master-wheel K is internally toothed and is about three times aslarge as the gear-wheel E, and is in a different verticalplane from thesaid gear-wheel.

L is a differential pinion-that is, itis composed of two toothedsections Z and Z, which are designed to mesh with the master-wheel K andwith the gear-wheel E. This pinion is mounted on a stud-shaft M, whichis adapted to be moved a greater or less distance from the axis of thechurn to permit the substitution of alarger or smaller pinion for thatshown when it is desired to vary the relative speeds of the dasher andthe churn-body. For the sake of simplicity of construction, thedifferential pinion L is reversible on the stud-shaft M, and the latteris adjustable to and from the axis of the churn by shifting it from oneto the other of the series of openings m provided iu the standard towhich it is secured. (See Fig. 2.)

The dasher is composed of segmental or crescent-shaped wings O, whichare perforated to facilitate the churning process.

The churn maybe operated by a crank applied to either journal I or tothe journal F, or to both. l

Motion is transmitted from master-wheel K to the gearvheel E throughpinion L, and drives the churnbody in a reverse direction to theflasher, as will be readily comprehended.

The barrel top or churn-cover issecured in place by two oppositely-curved bars P, the ends of which pass through staples p, near the edgesof the cover and engage with hooks Q, secured to the churn-body. Thecam-lever R, for operating the bars P, is journaled between thestandards fr, which pass through openings in said bars and are securedto the cover. The links S' connect the bars P midway of their ends withthe cover.

IIaving Ithus described my invention, what I claim, and desire to secureby Letters Patent, is@

l. In a churn, the combination, with the frame, the churnbody, anddasher concentrically j ournaled, the dasher-shaft passing IOO looselythrough the hollow journal of the ehurn-body, of the master-wheel K,secured on the dasher-shaft, the gear-wheel E, held on the journal ofthe churn-body, and the interchangeable differential pinion adapted tomesh with the gear-Wheels K and E to vary the relative speeds of thechurn-body and dasher, substantially as described.
